Judging by the questions you're asking about the PE format, you'll find this article[^] and this one[^] very useful.

as subject.
how does a class allocated in memory image?
i.e.
class A{
public:
A(void);
virtual ~A(void);
public:
virtual void someMethod(void);
virtual void someMethod2(void);
public:
void someMethod3(void);
void someMethod4(void);
private:
int m_nMenber;
};
A a;
how does these virtual functions and normal functions and member data allocate in memory as part of a.
more complicate:
class B : public A{
public:
B(void);
~B(void);
public:
virtual void someMethod(void);
virtual void someMethod2(void);
public:
void subClassMethod(void);
};
B b;
how does new inherited functions and new created functions allocate in memory as part of b,which is inherited from A?
any professional help would be appreciated!

Hello
Can any body tell in detail what is relative virtual addressing and all its basics?
Why virtual addressing is needed? How RVA invlolves in execution of PE files(EXEs,DLLs and so on..)

When the loader loads a DLL or EXE the address it loads it at (the base address) plus the RVA of something of interest in the image will give you its address in memory. Put another way, it's the location of something in memory relative to the base address of the containing module. Remember that DLLs can be relocated if need be so the base address need not always be the same.

See, for instance: "An In-Depth Look into the Win32 Portable Executable File Format" (have a look at "Relative Virtual Addresses" section).

Hi All,
I am beginner to MFC programming. I created one CLR Console Applications project, here in this project I want to use MFC classes like CString,CArray,CFile....etc.
In project settings I used "Use MFC in a shared DLL"
And in project stdafx.h file I am adding
#include<afx.h>
I also used few classes from MFC in the application and complied, I am not getting any errors.
But while running the application, I am facing crash in the application. and the error message is as follows
An unhandled exception of type 'System.AccessViolationException' occurred in Unknown Module.
Additional information:Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Please provide some solution for this.
Thanks in advance.
Regards,
Kumar

You shouldn't need to use the MFC classes in the application.
CLR provides several classes for the same like String, Array, File etc.

How are you writing to the first 2 columns?

I am using Excel Automation for that.. but i am trying to close the excel file and then open it again in a different function and then i am trying to append it again. that is not happening. I am using PutElement function to write the values into the excel file. but i am getting an exception there.

Hi,
I am developing a application in pure win32. I want to set font for Static control. How can I do this?
|
|
|
|
|
I think you can use SetFont() function in MFC and use WM_SETFONT message for pure Win32.
|
|
|
|
|
Just to expand on Rajeesh's answer, read up on CreateFont, CreateFontIndirect, as well as WM_SETFONT.
Don't forget to keep the HFONT somewhere to tidy up after the static control is gone.
To get the font, I'd recommend SystemParametersInfo[^], as that filld in a structure with various fonts the system uses. That way you can keep the look and feel consistent.

I guess he may use the WM_GETFONT message for the purpose...

Not if the static window has gone *poof* he can't...
I'm always happy for people to ignore my advice though - as long as they've thought about it before rejecting it. After all, it does not always apply! (see your sig for more details)

Send the WM_SETFONT [^] message.
